B-e it="knownrthat LJEAN BAPTIsTE BOIS- .s E- Lo'li a citizen of France,-'resi ding No. 402 East OneHundred and Sixteenth street,.

NewXork. ci ty in the county of New York and State of New York, have invented certain\ I new1andusetulf'1mprovements in Electric Ignlfter s. for;lilxplosive-Engines, of which the Toll-owiifgisa "specification, reference being had; therein; to the accompanying drawings.

This invention relates generally to explo- 'sive-moto-rs 'usi rig' any of the well-knownhydrocarbon's and in which the ex losive mix ture is 1' gnited by an electric spa! and adapted for use in stationary and other motors and automobiles.

ing or electric igniting regulator or circuitbreakercapable of minute adjustment to govern the time ofignition of the explosive mix- 'tnre.

The practicaleiubodiment of the improve-'- ments 'is illustrated in the accompanying I in g-reg ulator or circu it -breaker R is used may be of any suitable forin-such, for instance, as that illustrated and described in my pending application, Serial No. 32.693, filed Octo-- ber 11, 1900, of which this is a division.

The sparking-regulator or circuit-breaker R is carried by an insulated block 25, attached to the motor-framework adjacent a shaftlfi rotated by any suitable connection with some moving part of themotor. This block is preferably formedof ind n rated wood composed of pnlverizedebony agglutinated and vnicanized under high pressure and heat with a mix ture of beef-blood. The insulated block 25 supports .a bracket 26, as shown in Figs. 1 to 4-,. between the arms-oi which is mounted a .lever27on a cross pivot-rod9 for easy movement; I endo fthe lever-27 carriesa plain v said block. It more particularly relates to the spark-..

Fig. 4is a side num-pointed contacbscrew-2 8 to meeta like pointed terminal pro-videdby the plate. (See Figs.'l to 3.) The-othenend'of the leversup- 1 ports an antifriction roll 30,. arranged in the ,path of a rotating cam 31, secured to the outer .e ndoftheshaft. l6 and heldto duty against the cam by a suitable spring 32, underlying the lever" 37; e The roll is mounted with its axis atright' angles'to that of the cam..

To efiect the adjustment of the position'of the-roll of the lev er 27 ,with respect to the configuration of the cam-31 the insulated bloclt 25,'wi'th the lever, may be oscillated about the axis of the cam and clam ped in place by m w bolts'35, which pass through curved slotsin In the modified form otcirciritbreakerR (shown in Figs. at and-5),the direction of move" ment of the lever 27 is reversed and the-"cam J instead of h'a'vinga cot-away portion to allow.

contactof the termim iis provided-for bythe end of a rotating cam-36. v is reversed and the fixed terminal is carried by an overlying-bridge-plate 37, which in turn is connected to the plate 29. l

The contact-screw The primary circuit (shown in connection with Fig. 4) leads from one pole oi the bat: tery or other gene1'aton33 to the terminal plate 29, to the contact-screw 28 when permitted by the shape of the cam 3l'and the action of the spring on the lever, thence by the lever to-the transformer 34:. The other pole of the battery also leads to the transformer.

In the induced circuit one wire 0: leads to the binding-poste of an y proper igniting-plug, as in my said pending application, and the other to; the motor-framework, (represented by the disk 'y, Fig. 4.)

What I herein claim is- 1. In an explosive-motor, the combination of an insulating'blocx capable of oscillatory adjustment about a center and having curved slots with.engagingciampingebolts to lix the block in its adjusted position, an electric tel minal carried by the block,- a piyotaliy-mount- -edcircuit-breaking lever also carried by the block having at one end a contact and at the opposite end a roll, and a rotating cant engaging saidroll forvibrati-ng the lever, as de scribed.
